Citrus and Mushroom Chicken

6 skinless, boneless chicken breast halves (about 1-1/4 pound total)
1 1/2 cups water
3/4 cup frozen Florida Orange Juice Concentrate, thawed
3 tablespoons balsamic vinegar or white wine vinegar
2 tablespoons cornstarch
2 teaspoons instant chicken bouillon granules
2 tablespoons olive oil
4 cups sliced shiitake or button mushrooms
12 ounces refrigerated fresh or packaged dried tomato linguine and/or plain linguine, cooked and drained
Florida Orange Slices, halved (optional)

Rinse chicken; pat dry with paper towels. Season chicken breasts lightly with salt and pepper. For sauce, in a bowl stir together water, thawed concentrate, vinegar, cornstarch, and bouillon granules; set aside. In a 12" skillet cook chicken in hot oil for 8 to 10 minutes or until tender and no longer pink, turning once. Remove chicken from skillet; cover and keep warm. In the same skillet cook mushrooms until tender. Stir sauce and add to skillet. Cook and stir until thickened and bubbly. Cook and stir for 2 minutes more. Serve sauce over chicken and hot cooked linguine. If desired, garnish with orange slices. Makes 6 servings.
